• the road. At the present time, these restrictions include hauling only during three posted time periods <br />on weekdays and no weekend haulage from April 15 to December 15. <br />Secondary Access Roads <br />The two short access roads to the Whirlwind off of 5/10 Road will remain in their current <br />configuration as shown on Map C-lA. The Packrat portal will be accessed by reopening a previously <br />reclaimed mine access road off of 5/10 Road (see Map C-2). Reopening of this road was completed in <br />May 2007 during the exploration phase of the project. The 10-Straight vent shaft will be accessed by <br />an existing secondary road and two-track road off of 5/10 Road. The proposed vent shafts are located <br />next to existing roads and the access roads are included within the proposed 100-foot by 100-foot pad <br />area (see Map C-1 B). <br />The access roads to the portal areas within the mine permit will be dirt and/or gravel and bermed in <br />accordance with MSHA regulations. The roads into the Whirlwind and Packrat will have swinging <br />• metal gates. Gates will be locked during weekends, holidays, and other down times. The short access <br />roads to ventilation shafts and power drops will typically be two-track overland roads that will only be <br />used for periodic inspections and maintenance. No fencing or gates will be required at these sites. <br />Mine Pad Areas <br />The Whirlwind pad, as previously discussed, will have two levels. The lower level will be at <br />approximately the same elevation as the portal while the upper level will gradually move up the side of <br />the hill to the east. This upper level will be built from waste rock hauled from the mine. <br />The Packrat pad will be relatively small (approximately 1.0 acre in disturbed area) and terraced to <br />provide two levels as shown on Maps C-4 and C-5. The cut and fill for the portal area is an <br />approximate balance of 3,200 cubic yards. Two 30-ton metal bins for storage of waste rock and ore <br />will be installed so that the buggies can dump into the bins at the top level and haul trucks can pull <br />under the bins on the lower level and be loaded. An additional pair of bins may also be installed at a <br />• later date if needed. See Map C-4 for a plan view of the mine layout. The upper pad will have a ramp <br />Whirlwind Mine 07 (rev.
